<p>4-Methylumbelliferyl 4-O-(alpha-L-fucopyranosyl)-beta-D-galactopyranoside is a fluorogenic substrate for alpha-L-fucosidase. After enzymatic cleaveage, free 4-methylumbelliferone (also known as hymecromone) is released, exhibiting blue fluorescence upon excitation with UV light. The strongest fluorescence of 4-methylumbelliferone requires deprotonation of the hydroxyl group (thus requires alkaline pH), with a maximal fluorescence intensity obtained with excitation at 350 to 370 nm and emission at 440 to 470 nm. The use of 4-methylumbelliferyl 4-O-(alpha-L-fucopyranosyl)-beta-D-galactopyranosideas a substrate for measuring the alpha-L-fucosidase activity is used for fucosidosis diagnosis and in screening studies of glycoprotein metabolism disorders.</p>
